I asked Aishah رضی اللہ عنہا , mother of the believers: With which (surah) the Messenger of Allah صلی ‌اللہ ‌علیہ ‌وسلم used to observe witr? (She reported same as in the Hadith of Ubayy ibn Kab, No. 1418) This version adds: In the third rak'ah he would recite: Say, He is Allah, the One (Surah 112), and Say, I seek refuge in the Lord of daybreak (Surah 113), and Say, I seek refuge in the Lord of mankind (Surah 114).
